Abstract

Procédé de transformation d'une vue « d'origine » d'un modèle tridimensionnel numérique « d'origine », en une vue hyperréaliste, ledit procédé comportant les étapes suivantes : 21) création d'une base d'apprentissage « de transformation » constituée de plus de 1 000 enregistrements « de transformation », chaque enregistrement de transformation comportant : - une photo « de transformation » représentant une scène, et - une vue d'un modèle tridimensionnel numérique « de transformation » modélisant ladite scène, ou « vue de transformation », la vue de transformation représentant ladite scène comme la photo de transformation ; 22) entraînement d'au moins un réseau de neurones « de transformation », au moyen de la base d'apprentissage de transformation ; 23) soumission de la vue d'origine audit au moins un réseau de neurones de transformation, de manière qu'il la transforme en une vue hyperréaliste.
